A simple easy to implement algorithm is proposed to address wall tracking task of an autonomous robot. The robot should navigate in unknown environments, find the nearest wall, and track it solely based on locally sensed data. The proposed method benefits from coupling fuzzy logic and Q-learning to meet requirements of autonomous navigations. Fuzzy if-then rules provide a reliable decision maki...

This paper presents simulation and experimental results of position-based visual servoing control process of a 6R robot using 2 fixed cameras. This method has the ability to deal with real time changes in the relative position of the target-object with respect to robot. Also, greater accuracy and independency of servo control structure from the target pose coordinates are the additional advanta...

When studying the dynamic, physical interaction of robots with the environment a generic physics simulator becomes most important when robot and environment exceed a certain complexity. Investigation of current problems in robotics, e.g. in multifingered manipulation or two-legged walking requires simulations which reflect physical details of the real robot system in a virtual scene. The develo...

a general robotic mechanism was presented for in-pipe inspection oflevel pipes with varied diameter or curved pipelines. the robot employed three legs comprised of parallelogram linkages mechanism which enables adapting to various elbow joints in the piping systems. the curvatures in pipeline are the most important constraints in front of the robot through navigation process. to study the adapt...

We describe a simple cost-effective technique for the transport of binary vector plasmid DNA by mail. Our results demonstrate that common multipurpose printing paper is a satisfactory substrate and superior to the more absorbent 3 MM chromatography paper for the transport of plasmid DNA through the mail. We show that depositing as little as 100 ng of purified plasmid onto multipurpose printing ...

this paper presents a delay compensator fuzzy control for trajectory tracking of omni-directional mobile robots. fuzzy logic control (flc) of the robots is a suitable strategy for dealing with model uncertainties, nonlinearities and disturbances.  on the other hand, in many robotic applications such as mobile robots, delay phenomenon is able to substantially deteriorate the behavior of system's...
